Quite a large bunch of us here at MDA and other Paleo websites have numerous questions about AF quite regularly. Nearly everyone seems to inevitably suffer from this condition at some point in their lives to varying degrees of severity, and I'd love to see Mark tackle this somewhat controversial topic (mainly due to skepticism of its legitimacy). It'd be particularly great to see if he can analyse specific tips that most people agree are beneficial when attempting to heal, i.e. increasing carb intake; increasing salt intake; reducing the intensity of workouts; always sleeping early, preferably before 10 p.m; eating meals regularly around the clock without even thinking about intermittent fasting, etc. etc.

If he could provide a 'modified' Primal plan for AF sufferers, that would be the icing on the cake. I'd love to see his view on the subject in general, really.
